A homeless Kansas City man who returned an engagement ring a woman accidentally dropped in to his cup last Friday is reaping the benefits of the mantra “do unto others as you would have them do unto you.”

For Sarah Darling and husband Bill Krejci, simply thanking Billy Ray Harris (pictured) for holding on to their ring wasn’t enough. Nor was giving the homeless man all the money they had the day he returned it to them. So days later, they decided to step it up, starting a financial support campaign for Harris.
